Lead Time Deviation from Expectation

\mathit{LTDE}(c, \mathit{val})

Dimension:

Time

Granularity:

Case

Absolute value of the difference between the time that a case is expected to take and its lead time.

Event log is associated with a process in which the lead time of a case should be as close as possible to a specific value.

A lead time that is closer to the expected value is desirable.

$|val - \mathit{LT}(c)|$

\ $val$ represents the expected time value.
$\mathit{LT}(c)$ returns the lead time of case $c$ .

$|\mathit{val} - \mathit{LT}(c)|$

This indicator is implemented in the process_performance_indicators Python library.
